When using large models, building a comprehensive finite element (FE) numerical model able to simulate the portion of a containership whose extension in length is sufficient to properly evaluate combined loading effects is rather time consuming, and assigning proper boundary conditions representing the distribution of actual forces and moments on the hull girder is a challenging task. In this paper, the effect of shear stress distribution on the structural components of the hull girder is analyzed. At first, finite element (FE) models simulating a suitable length of the hull girder are considered. Later, smaller models of stiffened panels are extracted from the hull girder models and analyzed. The aim of this work is to investigate the shear stress distribution originating in the entire cross section and to build a smaller model extracted from a selected portion of the ship where hull girder collapse is supposed to initiate.
